At a glance

Analyze option spread strategies like vertical spreads, iron condors, straddles, strangles.

  • User asks about spreads
  • SKILL.md covers Instructions, Strategies and Options, Output and Dependencies, plus 1 more section
  • Runs Python scripts from its folder; calls uv
  • Multi-leg strategies

What it does

Spread Analysis is an agent skill from staskh/trading_skills. Analyze option spread strategies like vertical spreads, iron condors, straddles, strangles. Use when user asks about spreads, multi-leg strategies, vertical spread, iron condor, straddle, strangle, or strategy analysis.

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/spreads.py`).

It sits in Business, Finance & HR. The repository describes itself as: Claude powered advisor system for option traders. The licence is MIT.

When your agent uses it

  • User asks about spreads
  • Multi-leg strategies
  • Vertical spread
  • Strategy analysis

Example prompts

  • “/spread-analysis”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit b71a74f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Spread Analysis loads about 486 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 127 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~486

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
